• Israeli Researchers Say They Can Make Disinfectant from Tap Eater

    Researchers electrify water to produce hypo chloric acid at defined level of acidity; patented method has not been published in science journal or subject to peer review. Shoshana Solomon writes in the Times of Israel that researchers at Bar-Ilan University have developed what they say is a new way to make strong and environmentally friendly disinfectants to kill bacteria and viruses by using just tap water. The disinfectant materials were recently tested by researchers in the virology labs of Prof. Ronit Sarid of the Mina and Everard Goodman Faculty of Life Sciences at the university and at the Poriya Hospital in the north of Israel, and were “proven effective” in neutralizing microbes, fungus and corona-type viruses, Aurbach said in a phone interview.

  • France, Europe Mull Controversial Coronavirus Tracing Apps

    France’s parliament votes next week on plans to use a controversial tracing app to help fight the coronavirus, as the country eyes easing its lockdown next month. Lisa Bryant writes in VOA News that French Digital Affairs Minister Cedric O says the downloadable app would notify smartphone users when they cross people with COVID-19, helping authorities track and reduce the spread of the pandemic. In a video on the ruling party’s Facebook page, O said the so-called “Stop COVID” app will fully respect people’s liberties, and will be completely voluntary and anonymous. It also will be temporary — lasting only as long as the pandemic, he added. The government wants to launch the app on May 11, the date it has set to begin easing a two-month lockdown in the country. It initially announced a parliamentary debate on the technology, but that’s been changed to a vote, after major pushback from lawmakers.

  • NIST Tool Could Help Hospitals Repurpose Rooms for Disinfecting N95 Masks

    In response to the COVID-19 pandemic, hospitals across the United States are disinfecting N95 masks by placing them in repurposed rooms or shipping containers injected with a disinfectant known as vaporized hydrogen peroxide, or VHP. A new tool from the National Institute of Standards and Technology (NIST) can help hospitals and medical professionals determine which rooms should be used to disinfect N95 masks. The tool estimates the amount of VHP masks would receive and suggests that larger rooms containing fewer objects, with less-reactive surfaces and slower ventilation, maintain VHP concentration the best.   

  • Self-Powered X-Ray Detector Improves Imaging for Medicine, Security, Research

    A new X-ray detector prototype is on the brink of revolutionizing medical imaging, with dramatic reduction in radiation exposure and the associated health risks, while also boosting resolution in security scanners and research applications. 2-D perovskite thin films boost sensitivity 100-fold compared to conventional detectors, require no outside power source, and enable low-dose dental and medical images.

  • How Will the Pandemic Affect National Security Innovation

    The second week of March was an inflection point for many across the world. Rachel Olney writes that as a founder of a tech company with commercial and defense customers, she has concerns for the early-stage companies with defense applications. With the massive economic downturn came panicked investors trying to determine which companies in their portfolios would survive. “They reached out to learn how much cash we have, if we can do layoffs, and if we would ultimately survive,” she writes. “My experience was not unique.”

  • Israel Launches New “Contactless” Roadside CPVID-19 Testing Booths Which Have Zero Contact between Nurse and Patient

    Israel has launched a network of new ‘contactless’ roadside covid-19 testing booths which have zero contact between nurse and patient. The Daily Mail reports that the country has offered to share the design, which is relatively cheap and easy to produce, with other countries as part of the fight against the coronavirus pandemic. The booths, produced by healthcare companies together with civilian and military partners, provide an entirely sealed, sterile environment for the medic, and can be quickly disinfected between patients. Tests are carried out using two rubber gloves which are attached to the outer wall with airtight seals. Results are processed in a matter of hours and reported directly via the patient’s electronic health record.

  • Toward an Unhackable Quantum Internet

    A quantum internet could be used to send un-hackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a quantum network have remained out of reach in large part because of the difficulty to send quantum signals across large distances without loss. Researchers have found a way to correct for signal loss.

  • Increasing Fire Protection through Virtual Reality

    Fire is one of the most dreaded anxieties in households worldwide. In 2018 Dutch insurance companies registered no less than 80,000 domestic fires. The most common cause is smoking, followed by technical malfunctions in appliances and cooking. Preventive measures can avoid many of the consequences and there is a lot to be gained.

  • The Coronavirus Contact Tracing App Won't Log Your Location, but It Will Reveal Who You Hang Out With

    The Australian federal government has announced plans to introduce a contact tracing mobile app to help curb COVID-19’s spread in Australia. Roba Abbas and Katina Michael write in The Conversation that rather than collecting location data directly from mobile operators, the proposed TraceTogether app will use Bluetooth technology to sense whether users who have voluntarily opted-in have come within nine metres of one another. Contact tracing apps generally store 14-21 days of interaction data between participating devices to help monitor the spread of a disease. The TraceTogether app has been available in Singapore since March 20, and its reception there may help shed light on how the new tech will fare in Australia.

  • Strengthening Mobile Device Email Security and Privacy

    Large and small organizations alike now rely heavily on mobile devices like smartphones or tablets to enable their workers, customers and management to connect and collaborate, even when some or all of them are working remotely. But device users may prioritize convenience over strong security, accidently share sensitive information with unintended audiences, or use their corporate- or government-owned devices in contexts in which sensitive business information should not be shared.

  • System to Locate Rescue Forces in Distress

    In the event of fires, earthquakes, or in other emergency situations, rescue forces are often called to free persons caught in buildings. These rescue missions are very risky: Dangers are difficult to assess in advance and the helpers themselves may suddenly need help. To support them as quickly as possible, researchers have developed a system to locate injured or buried rescue forces in buildings. For positioning, no GPS signal is needed.

  • Tools to Help Volunteers Do the Most Good after a Disaster

    In the wake of a disaster, many people want to help. Researchers have developed tools to help emergency response and relief managers coordinate volunteer efforts in order to do the most good. The researchers used advanced computational models to address these areas of uncertainty in order to develop guidelines, or rules of thumb, that emergency relief managers can use to help volunteers make the biggest difference.

  • 5 Burning Questions about Tech Efforts to Track COVID-19 Cases

    The pitch from technology companies goes something like this: We can tap phone data to track Covid-19 infections in U.S. communities and swiftly warn people about potential exposure, all without ever compromising anyone’s privacy. Casey Ross writes in STAT that Apple and Google turned heads a few days ago when they announced a joint effort to bolster this public health service — a task known as contact tracing — by building software into smartphones that relies on Bluetooth technology to track users’ proximity to one another. Facebook is participating in a similar effort led by the Massachusetts Institute of Technology. While their brands give them instant credibility in the business world, infectious disease experts aren’t convinced the technology offers a tidy solution to such a complicated public health problem.

  • The Challenge of Proximity Apps For COVID-19 Contact Tracing

    Around the world, a diverse and growing chorus is calling for the use of smartphone proximity technology to fight COVID-19. In particular, public health experts and others argue that smartphones could provide a solution to an urgent need for rapid, widespread contact tracing—that is, tracking who infected people come in contact with as they move through the world. Proponents of this approach point out that many people already own smartphones, which are frequently used to track users’ movements and interactions in the physical world. But it is not a given that smartphone tracking will solve this problem, and the risks it poses to individual privacy and civil liberties are considerable.

  • Bluetooth Signals from Your Smartphone Could Automate COVID-19 Contact Tracing While Preserving Privacy

    Imagine you’ve been diagnosed as Covid-19 positive. Health officials begin contact tracing to contain infections, asking you to identify people with whom you’ve been in close contact. The obvious people come to mind — your family, your coworkers. But what about the woman ahead of you in line last week at the pharmacy, or the man bagging your groceries? Or any of the other strangers you may have come close to in the past 14 days? Researchers are developing a system that augments “manual” contact tracing by public health officials, while preserving the privacy of all individuals. The system enables smartphones to transmit “chirps” to nearby devices could notify people if they have been near an infected person.
